Returning JSON Error Field Name about jsonschema

[Julian]

Hey there.

So, have you gotten a chance to try this on the latest release (v0.4)? Assuming I haven't misunderstood, both of these should be available already. Perhaps the docs could use a bit more elaboration. For the failing validator and property, see ValidationError.validator and .path. Also check out the ErrorTree example in the README which is a bit easier to work with.

Let me know how it goes.

[Julian]

Any luck?

[Xeus]

Yes, thanks for following up! And yes, we used .validator and .path, appreciate it! We're now returning a dictionary through the (deprecated) iter_errors containing a human-readable error message, the field and its value triggering an error, and the property of the schema which was violated.

[Julian]

OK great. Yeah iter_errors isn't deprecated, it's the new thing that
replaces stop_on_error which is deprecated.

And the easiest way if you need to have a bunch of dicts would just be to
pluck the attributes off certainly.

# Note that this can raise KeyErrors if you've got
# errors that are due to missing required properties
# so you need to be slightly cleverer if you really
# want the value
errors = ({
    "validator" : error.validator,
    "message" : error.message,
    "path" : error.path,
    "value" : reduce(operator.getitem, reversed(error.path), instance)
} for error in Validator().iter_errors(instance, schema))
